Just wanted to run this one past the 'collected masses'. I have been working on a concept for a 'motor topper' that can be used on Hybrid Systems. The basic concept is a small chamber at the top of the motor with a check valve in it. When the hybrid motor is filled, the chamber fills with nitrous. At a set altitude or time, a valve or burst disk releases the nitrous into the rocket as a deployment charge.
Has a few advantages over pyro systems, including;
No pyro
low cost, no consumable parts other than the nitrous
safe handling until the motor is charged (safe to walk around with)
not subject to altitude ignition problems.
low volume / good location location on the rocket.
Safe and arm can be tied to motor pressure.
Problems as I see them,
How to 'disarm', possible pin hole leak or small vent valve.
Temperature issues.
Electronic system to open a valve?
Doesn't help for dual deploy
Any thoughts?
